Chapter 7: Virtual Media Guide 97
You can specify that the virtual media session is reserved. When a session is reserved, and the
associated KVM session is closed, another user cannot open a KVM session to that target device. If
a session is not reserved, another KVM session can be opened. You can reserve the session to make
sure that a critical update is not interrupted by another user attempting to preempt the KVM session
or by inactivity time-outs on the KVM session.
You can also reset the KVM server module from the Virtual Media window. This action resets
every form of USB media on the target device, and should be used with caution only when the
target device is not responding.
Virtual media session settings
Virtual media session settings include locking, mapped drives access mode and encryption level.
Table 7.2 lists and describes the virtual media session settings.
To open a virtual media session:
1. Open a Video Viewer session to the target device.
2. From the Video Viewer toolbar, select Tools - Virtual Media. The Virtual Media window
opens.
3. If you want to make this a reserved session, on the Virtual Media window click Details, then
select the Reserved checkbox.
To map a virtual media drive:
1. Open a virtual media session from the Video Viewer toolbar by selecting Tools - Virtual Media.

Setting Description
Locked The Locked setting specifies whether a virtual media session is locked to the KVM session
on the target device. When locking is enabled (which is the default) and the KVM session is
closed, the virtual media session also closes. When locking is disabled and the KVM
session is closed, the virtual media session remains active.
Mapped drives
access mode
You can set the access mode for mapped drives to read-only. When the access mode is
read-only, you cannot write data to the mapped drive on the client computer. When the
access mode is not set as read-only, you can read and write data from or to the mapped
drive.
If the mapped drive is read-only by design (for example, certain CD drives, DVD drives, or
ISO images), the configured read-write access mode is ignored.
Setting the read-only mode can be helpful when a read-write drive such as a mass storage
device or a USB removable media is mapped, and you want to prevent the user from writing
data to it.
Encryption
level
You can configure up to three encryption levels for virtual media sessions. Any combination
is valid. The choices are: DES, 3DES and 128-bit SSL. The highest level selected is used.
The default is no encryption (no encryption levels selected).
